Alpha-Synuclein Biomarkers Across Saliva, Skin, and CSF Show Diagnostic Promise for Parkinson's Disease
Alpha-synuclein biomarkers in saliva, skin, and CSF show diagnostic promise for Parkinson's disease, with seed amplification assays demonstrating high sensitivity and specificity. Salivary gland biopsies and oral brushings are being studied as less invasive detection methods, though clinical implementation still faces challenges.
